Yes, 87 88 and 89 are interchangable
Should it matter that the 1500 only has the 4.3 v6 in it?
Not if it's not a V8
The computer will not comunicate with V8, emissions etc
I'd probably have to switch out wiring and such too right
I should have added I'll have the whole 2500 for any parts that I need
the engine should mount up with no problems. you will have to swap out the wiring and sensors ect...
